Ce serait bien un comportement de FeatureJoiner si on en croit l'aide de ce

Join Behavior
A Joined feature is produced each time a Left feature is matched to a Right feature
through its keys. The number of output features produced will depend on whether or not
multiple Left and Right features match.
The type of join is determined by the nature of the data used (it is not a parameter). Any
of these types of joins may be produced by any of the Join Modes (Inner, Left, or Full).
[...]
M:N Many to Many: If multiple Left features match multiple Right features (for example a
number of addresses match to a number of records for electrical power outages) this is a
M:N (many-to-many) match and produces a Joined feature for every match that occurs.
10 Left match 10 Right:
100 Joined Features output*
*When all features have identical key values - all Left match all Right.

FeatureMerger ne se comporte pas pareil.
